Molecular Staging Estimates Occult Tumor Burden In Colorectal Cancer, Alex Mejia, Stephanie Schulz, Terry Hyslop, David S. Weinberg, Scott A. Waldman

Department of Pharmacology and Experimental Therapeutics Faculty Papers

Tumor cells in regional lymph nodes are a key prognostic marker of survival and predictive marker of response to adjuvant chemotherapy in colorectal cancer. However, clinicopathologic techniques to detect lymph node metastases remain imperfect, and ~30% of patients with lymph nodes negative by histology (pN0) develop recurrent disease, reflecting occult metastases that escape detection. These observations underscore an unmet clinical need for accurate approaches to identify occult nodal metastases in colorectal cancer patients. GUCY2C is a receptor whose expression normally is restricted to intestinal epithelial cells, but is universally over-expressed by colorectal cancer cells. A prospective, multicenter, blinded clinical trial …

A Novel Curriculum Using Simulation To Teach And Assess Indications And Technique Of Handwashing To Gme Learners, K. Berg, C. Sultana, R. Sorokin, J. Kairys, M. Vergare, D. Berg

Department of Obstetrics and Gynecology Faculty Papers

Proficiency in the clinical skill of effective hand washing is integral to high quality health care. Studies at our hospital revealed that in 2008, of 1215 direct, anonymous, observations of residents and attendings, only 53.3% washed their hands correctly during clinical activities. Medical students in fiscal year 2009 (July 1, 2008-June 30 2009) had a 52% compliance rate from 109 observations. This data prompted our hospital to work with the faculty of the University Clinical Skills and Simulation Center (UCSSC) to develop a module on the indications and technique of effective handwashing. This intervention, using multimedia simulation was introduced to …

Sustained Expression Of Tdp-43 And Fus In Motor Neurons In Rodent's Lifetime., Cao Huang, Pedro Yuxing Xia, Hongxia Zhou

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

TAR DNA-binding protein (TDP-43) and fused in sarcoma (FUS) are two highly conserved ribonucleoproteins. Pathogenic mutations of the TDP-43 or the FUS gene are all linked to amyotrophic lateral sclerosis (ALS) that is characterized by progressive degeneration of motor neurons. To better understand the correlation of ALS disease genes with the selectivity of chronic motor neuron degeneration, we examined the longitudinal expression of the TDP-43 and the FUS genes in C57BL6 mice and in Sprague-Dawley rats. TDP-43 and FUS were robustly and ubiquitously expressed in the postnatal mice and rats, but were markedly decreased in the adult rodents. In adulthood, …

Effect Of Visual Media Use On School Performance: A Prospective Study, Iman Sharif, Md, Mph, Thomas A. Wills, Phd, James D. Sargent, Md

Department of Pediatrics Faculty Papers

Purpose: To identify mechanisms for the impact of visual media use on adolescents' school performance.

Methods: We conducted a 24-month, four-wave longitudinal telephone study of a national sample of 6,486 youth aged 10 to 14 years. Exposure measures: latent construct for screen exposure time (weekday time spent viewing television/playing videogames, presence of television in bedroom) and variables for movie content (proportion of PG-13 and R movies viewed).

Outcome measure: self- and parent reports of grades in school. Effects of media exposures on change in school performance between baseline and 24 months were assessed using structural equation modeling. Information about hypothesized …

Reduced Mortality And Increased Bpd With Histological Chorioamnionitis And Leukocytosis In Very-Low-Birth-Weight Infants., David A. Paul, Md, Kelly Zook, Md, Amy Mackley, Rnc, Robert G. Locke, Do

Department of Pediatrics Faculty Papers

OBJECTIVE: To investigate the association between leukocytosis, mortality and bronchopulmonary dysplasia (BPD) in very-low-birth-weight infants (VLBW) born to mothers with histological chorioamnionitis.

STUDY DESIGN: A retrospective cohort study from a single level 3 neonatal intensive care unit. The study sample included infants born to mothers with histological chorioamnionitis (n=252). Total white blood cells (WBCs) after birth were measured. Leukocytosis was defined as a total WBC count >30 000 per mm(3) in the first 2 days of life. Outcomes investigated included BPD and death. Both unadjusted and multivariable analyses were carried out.

RESULT: After controlling for potential confounding variables, infants who …
